To set the time accurately to the second, it is best to stop the
movement as the seconds hand passes 60. The minute hand
and the 24-hour hand can now be set (the hour hand is set
separately with the crown in position 1). Now move the minute
hand a few minute strokes beyond the time to be set. Then
position the minute hand by moving it gently backwards until
it is exactly above the correct minute stroke. This ensures that
the minute hand begins to move immediately when you restart
the movement. To start the movement, push in the crown to
position 0.
